To aZZ whom it may concern:

Be it known that I, WALTER R. PAXSON, a citizen of the United States,residing at Glenside, in the county of Montgomery and State ofPennsylvania, have invented new and useful Improvements in Indoor Swings(Case B), of which the following is a specification.

This invention relates to swings and more particularly to a swing of theindoor type and supporting means therefor.

This invention is an improvement over the swing disclosed in myco-pendingapplication for swing, filed March 6th, 1922, Serial No.541,390.

The primary object of the invention is to simplify the supporting meansfor the swing and to so construct this supporting means as to obtainmaxmium strength and rigidity while providing a light structure whichmay be readily produced at small cost.

Further objects will appear from the detail description.

In the drawings Figure 1 is a front view of the swing as applied.

Figure 2- is a side view of the swing supporting means.

Figure 3- is a longitudinal through the supporting bar.

Figure 4 is a section taken substantially on line 4-4 of Figure 3.

I provide a cross bar 1 which is of channel cross section and may bereadily made from sheet metal of suitable gauge so as to section bereadily produced at small cost. This bar has its web portion cut andbent downwardly to provide ears 2 spaced away from the end walls 3 ofthe bar, these ears being provided with openings 4 disposed in alignmentwith similar openings 5 through the end walls 3. The openings 4 and 5receive pivot bolts 6. Each of the bolts 6 passes through alignedopenings provided in the lower portions of arms 7 of a pair of tongs 8.Each arm 7 is provided at its upper end with a substantially l..-shapedelement 9 adapted for engagement over the upper lateral portion of across beam A of a door frame or similar structure, this cross barprojecting beyond the sides of wall B or a similar structure with whichthe frame is associated.

As will be noted more clearly from Figure 1923. Serial No. 654,738.

2, each of the arms 7 is provided, in its lower portion, with aplurality of spaced openings 7 for reception of the pivot bolts 6. Thisprovides simple and efficient means whereby the arms may be readilyadjusted relative to cross bar 1 to accommodate the particular beam A inconnection with which the device is to be used.

A nipple 10 is secured through the center of web 1 of cross bar 1 bymeans of nuts 11 and 12 threaded on to this nipple above and belowweb 1. This nipple is interiorly threaded to receive a pressure screw 13provided at its lower end with an eye 14, and at its upper end, with aswiveled head 15 adapted for engagement with the underfacc of cross beamA. The nuts 11 and 12 serve to secure the nipple in position and alsoact to reinforce web 1 about the nipple so as to prevent bending ordistortion of the web by the pressure exerted by the pressure screw 13.Each end wall 3 of bar 1 is provided with a lower opening 16 adapted forreception of an S-hook 17. Ropes 18 are passed through the hooks 17 andhave their lower ends secured through similar hooks 19 which passthrough plates 20 secured to theends of a seat-board 21 at the front andback thereof. This provides simple and efficient means for supportingthe swing and, as the bar 1 is positioned centrally of the tongs, theline of strain will be vertical or substantially so, so that there is notendency to pull the arms of tongs 8 away from cross beam A. hen thedevice is applied, pressure screw 18 is threaded through nipple 10 so asto exert downward pressure on bar 1.. thus effectually securing thetongs in engagement with the cross beam, as will be understood. If it isdesired to use a swing having a single rope, the rope may be insertedthrough eye 14 of the pressure screw. Preferably, though notnecessarily, I provide collars 22 of rubber or other suitable materialabout the outer portions of elements 9 to prevent marking or scarring ofthe lateral faces of cross beam A.

The device constructed in the manner illustrated and described,possesses great strength and rigidity and may be readily produced atsmall cost. By providing the ears 2 for receiving the pivot bolts 6,these bolts are efiectually braced and the end walls 3 are relieved, toa great extent, of excessive strainswhich would tend to distort theseend walls or bend them inwardly of bar 1. What I claim is: r r in adevice otthe character described, a

cross bar of channel crosis SQtlOD, said hzrr being provided with end\VilllS and with int cg al dmvnwardly directed ears spaced away tromsaid end WflllS, pairs of tones at, the ends of the bar, pivot membersextending" through the respective tones and secured through the endwalls and ears ol said bar. 0

a nipple extending through the web portiou of the har eentrallv thereof.securing nut threaded (Hrs-aid nipple and conlaetiug with the upper andlower faces of said weh portl()1],'21l1(l a pressure screw threadedthrough said nipple.
